On 1 Aug 2025, the Subcommittee of Intelligent and Connected Vehicles under the National Technical Committee of Auto Standardization (SAC/TC114/SC34) opened a public consultation for two ICV-related voluntary national standards:
- 20243207-T-339 Technical specification for digital key system of vehicles
- 20243203-T-339 Intelligent and connected vehicles – Data security management system specification.
- 20243207-T-339 Technical specification for digital key system of vehicles
- What is the standard about?
This standard stipulates technical requirements and test methods for digital key system of vehicles. A digital key of vehicles refers to a digital credential managed by a digital key system of vehicles, stored on a physical device, and authorized by the primary user. Here, the primary user is one who holds authorization permission for vehicle usage. The physical device is typically a smart mobile terminal or wearable device, such as a smartphone, smartwatch, or smart band.
The digital key system of vehicles consists of the physical device, an application, an in-vehicle digital key module, and a server system. It uses wireless communication technology to enable information exchange between the authorized device and the vehicle, allowing functions such as locking/unlocking the doors and starting the vehicle.
- Why is the standard needed?
Currently, the digital vehicle key industry chain faces issues such as inconsistent terminology and a lack of standardized testing protocols. These challenges not only increase the difficulty of coordination among automakers, system integrators, and other upstream and downstream players, but also hinder the large-scale adoption of digital car key technology. Furthermore, they negatively impact the user experience.
The development of this document aims to:
- Ensure the stable performance of digital vehicle key-related products by providing enterprises with clear development and testing guidelines.
- Help improve product quality and promote the high-quality development of China’s digital car key industry.
According to TC114/SC34, there is no international standard present that specifically applies to functional requirements, performance evaluation, and test methods for digital key system of vehicles. Therefore, this standard has not adopted any international or foreign standards.
- 20243203-T-339 Intelligent and connected vehicles – Data security management system specification
- What is the standard about?
This standard will apply to vehicle data processors. The standard stipulates the requirements for organizational vehicle data security management, the management of relevant parties’ vehicle data security activities, full lifecycle management of vehicle data, monitoring and handling of vehicle data security, engineering of vehicle data security, and vehicle data security risk assessment. It also describes the corresponding verification methods.
- Why is the standard needed?
This standard aims to promote the automotive industry to establish and improve the data security management system for intelligent and connected vehicles. By adhering to its requirements for secure product development and data security management, enterprises can enhance their overall data security capabilities, elevate the data security and governance level of the entire automotive sector, and provide managerial solutions to address data security challenges in intelligent and connected vehicles.
The development and implementation of this standard will provide technical support for safe development to automotive manufacturers, suppliers, and service providers, guiding them in meeting industry data security requirements for vehicles and related products. It is essential for strengthening data security management across domestic automakers, suppliers, and service providers, assisting them in complying with domestic and international regulatory requirements, and enhancing the market competitiveness of their products.
In 2024, TC114 published a voluntary national standard GB/T 44464-2024 General requirements for vehicle data. This standard established a framework for automotive data security management systems.
20243203-T-339 Intelligent and connected vehicles – Data security management system specification will build upon the requirements from GB/T 44464-2024, by providing detailed specifications for the establishment and operation of data security management systems specific to intelligent and connected vehicles.
This standard does not adopt or modify any international standards. However, the formulation of this standard has referred to 7 international standards.
SESEC will continue to monitor the development progress of these two standards and provide timely updates once the standards are officially released.
